The National Immigration Law Center has a short guide on how the Affordable Care Act (ACA) applies to immigrants. The guide notes that naturalized citizens have the same access and requirements for affordable coverage as US-born citizens, lawfully present immigrants have limited federal coverage depending on the circumstances, and undocumented immigrants are not eligible for federal coverage, as noted in our previous post. Think Progress also has a (more detailed) guide on health insurance options for immigrants under the ACA.
